Abstract:

PURPOSE: Assess the effect of intensive vs conventional blood pressure goals on patient-important outcomes in older adults with type 2 diabetes. METHODS: A comprehensive search was performed using electronic databases. Randomized controlled trials comparing intensive vs conventional blood pressure goals in adults over 60 years of age with type 2 diabetes were included. Events were evaluated using a modified Mantel-Haenszel meta-analysis with Peto's method. Study selection and data extraction were performed independently and in duplicate. RESULTS: Seven trials were included. A 19% risk reduction (OR 0.81; 95% CI 0.69-0.95; I = 8%; p = 0.35) in the occurrence of major adverse cardiovascular events (MACE) and 37% risk reduction (OR 0.63; 95% CI 0.51-0.79; I = 0%; p = 0.56) in the occurrence of fatal or non-fatal stroke was documented in the intensive treatment group. There were no differences in the occurrence of all-cause mortality, cardiovascular mortality, non-fatal myocardial infarction, and peripheral vascular disease. Data regarding treatment adverse effects and microvascular outcomes was scarce. CONCLUSIONS: Intensive blood pressure goals in older patients with diabetes were associated with a lower risk of stroke and MACE, but not with all-cause mortality, cardiovascular mortality, non-fatal myocardial infarction, and peripheral vascular disease.
